Last weekend, our niece came over from Spokane with her partner and his 7 year old child. It only took these two about 10 minutes to decide they were cousins, and they were thrilled to be in each other's company. They played baseball countless times, practiced with light sabers (another Star Wars fan is always an instant friend), and spent way too many hours playing Minecraft on the iPad. I cringe at that, but it did give us adults time to visit.
I loved best that he towered over her, and that they grew so attached after such a short time. They have plans to meet in their mutually created Minecraft world named Steve. Yes, that sounds weird. This might be a precursor for the teen years and social media.
